VPI Dry Type Power and Distribution Transformers

VPI Dry Type Power and Distribution Transformers VPI Dry Type Power and Distribution Transformers
(VPI Dry Type Transformer)
RANGE : Upto 5000 KVA upto 11 KV Class.

RUNTHALA INDUSTRIES offers a technologically advanced range of Dry Type VPI (Vacuum Pressure Impregnated) Transformers with Off Circuit Tap Links manufactured using CRGO M3 to M5 MOH lamination and an electrolytic grade copper. These transformers are designed for a trouble-free performance. Modern manufacturing techniques coupled with optimum utilization of active materials ensures cost effectiveness, reliability and a long trouble-free performance.
RUNTHALA INDUSTRIES Dry Type Transformers are fitted with enclosures for indoor installations.Therefore requires no maintenance and ensures safety from fire as the material used is metal, ceramic, NOMEX and resin. It is an eco-efficient product that requires no oil and thus reducing chances of spillages,leakage or nontoxic smoke emission in case of fire. The use of Class ‘F’ / ‘H’ insulation increases the heat bearing capacity and enables the use of the transformer in humid and chemically polluted atmosphere also.

Fire safety and environmental aspects are of increasing importance. The substitution of oil filled transformers by dry type transformers is one of the most important steps towards it. VPI transformer is used when it has to be located near load centre and in a fire hazardous place. Special type of fire resistant insulation is used for the windings, thus reducing the fire risk considerably.
